EMC vs EMI Testing

EMC, or Electromagnetic Compatibility, is the ability of a device to operate in an environment with other devices without affecting those devices. EMI, or Electromagnetic Interference, is when the electromagnetic output of a device disrupts the operation of another device.

Many people use EMC and EMI interchangeably as they both determine whether a device can coexist with other devices. EMC testing examines a product’s radio frequency (RF) emissions, and EMI testing its immunity to RF.

Meet the Regulatory EMC/EMI Requirements

EMC certification is a mandatory requirement in most markets. EMC testing measures the ability of equipment or systems to function satisfactorily in their electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment.

As an accredited NRTL certification provider, and an ISO/IEC 17025:2017 certified laboratory, TÜV SÜD can conduct conformity assessments to help strengthen your competitive position in the market.
